    I think you'll get a lot more satisfaction if you buy the tools and finish the build yourself.

    Tools you should buy, yourself you should do it, another vote for this is.

    $150 in tools fora barrel install? Negative. Gunsmith? Negative, do it yourself.

    Upper receiver blocks: $12.99 https://www.plastixrevolution.net/co...ver-vise-block
    Torque Wrench: $21.99 http://www.harborfreight.com/catalog...=torque+wrench
    Need a low-pro gas block dimple jig?: $30 http://slrrifleworks.com/index.php?r...ry&path=57_129
    I like a set of these, as they keep things from slipping in the vice, and useful for installing the receiver extension castle nut if you need to do a lower: $10 http://www.ebay.com/itm/like/1210819...&ul_noapp=true
    I also like a 3/4" crow's foot for putting on muzzle devices, but not necessary.

    That's about $75, and all you need, unless you completely lack tools. Vice, wrenches, allen keys, drill, etc.
    Tools to properly assemble a lower would not be that much more.

    What type of upper/lower are you planning on assembling? Parts list? Having the tools is great in case you need them, or need to help a friend.

    Hey Bachelor Farmer - if the name is accurate, you should be plenty handy enough to put it together yourself. Plenty of resources internet-wide and on here and other sites to get you through if you get stuck. There is a feeling of accomplishment in doing it yourself, and I doubt you will do just one.

    Good luck.

    ETA - right now Brownells has Geissele reaction rods on sale for 79.99.

    I have one of these, think I paid 49.00 for the rod only: https://www.botach.com/kley-zion-ar1...orers-package/

    I'm in agreement with all about getting the tools, its ultimately worth it. Primary Arms is running a 25% off sale on all things Geissele.

    Yeah, be like all us idiots, soon you'll have an AR for every room in the house and any application you can think of.
    Spend your days scouring EE's for parts.... "Hmm-i like my 12.5, but what if i did a 13.5..and hmmmm.... That dissipator looks like cool idea..."
    Get the tools, sell your soul, become a member of the cult.

    Awesome links & replies, thanks.
    Kind of agree about getting the tools & doing it myself.
    I didn't find vice blocks at that low of a price.
    All I have seen are $50.00 and up.
    I have a new Colt 16" barrel with A2 front sight already attached [came that way from Brownell's].
    So all I need to do is clamp it in a vice, torque the nut and align & pin the gas tube. [may need a few roll pin punches]?

    I will shop the links and thank you for listing them.
    Probably get to it after the holidays.

    What is the procedure to properly stake the receiver end plate with the castle nut?
    There has to be a trick to it?
    I can see that going wrong without practicing on a similar piece.
    Other than that, I'm sure I have the skills to assemble the AR...

    Castle nut is easy. Just stake the top 2 marks. Go straight down for the first couple whacks, then begin to angle slightly out and into the castle nut notches. Go slow and progressively harder hits on the punch. All you have to do is just barely displace the metal, you do not want to split/crack the end plate stake. Just Google some pics

    http://img.photobucket.com/albums/v5.../IMG_81072.jpg this 1 looks about perfect. Just don't get too close to the edge.


    1. Install Detent and Spring.

    2. Screw Reciever Extension onto Reciever while depressing Detent and Tighten Reciever Extension.
    - RIFLE: Use Torque Wrench, Part No. 94162 with Wrench,Combination Part No. 62696 (GI M16 Armorer Wrench) to apply Torque of 35-39 lb-ft.

    - CARBINE/COMMANDO: Use Torque Wrench, Part No. 94162 with wrench, Part No. 62420 to apply Torque of 38-42 lb.-ft.

    WHEN REASSEMBLING CARBINE OR COMMANDO Rotate Reciever Extension clockwise until it is flush or below Receiver and holding Buffer Retainer in place. Buffer Retainer should be free to move up and down. Install Takedown Pin Detent and Spring. Position End Plate and tighten Nut. After the Reciever Extension Nut has been tightened, the End Plate is to be staked with a center punch to any two of the Staking Slots in the Reciever Extension Nut. (Diagram shows upsetting the metal edge of the End Plate into the Slots in Reciever Extension Nut with a Center Punch.)

    A little bit more to it than the way you wrote above. Readers digest version below:
    1. Remove A2 FSB from the barrel. This requires a hammer, sturdy punch, and a solid block to brace the FSB on while driving the pins out.
    2. Place the barrel in the upper, and use receiver blocks to clamp the upper horizontally in a vice.
    3. Apply anti-seize to receiver threads, and torque barrel nut to receiver (Depending on type of hand guard, and barrel nut used, timing the barrel nut may, or may not be an issue).
    4. Once the barrel nut is installed and timed, if necessary, and depending on the type of hand guard being used, you may need to install the hand guard retainer cap/delta ring, or the entire hand guard.
    5. Then the A2 FSB can be re-installed (the gas tube needs to be installed to the FSB first, if it has not already been installed).

    Be sure to use a NON graphite based antiseize compound. Any EP moly based grease will suffice. I use nickel based antiseize.
